I have been searching the internet hi and low but cannot find any wokring solution to make Crysis 1 work under W7x64.
I bought the game directly from Origin, for the 64bit patch. But neither Vista/XP Admin Compatibility, or anything you find
usually on the nets, works.

The thing is the Game works just nice out of the box In Parallels 8 with XP Home 32 bit.
Well it *would* potentially run nice if my Mac was more powerful, for the testdrive I did it was only 7fps or so.

Doesn't work how? That's not much to go on. Plus: what exactly have you tried?

I'm betting your Intel graphics is the problem, though you don't even say that you're using either of the computers in your sig. Parallels might fool Crysis into thinking it can run, and maybe updating drivers might help under bootcamp, but 7fps isn't even worth it in a shooter. I tried running Crysis on my old gaming comp and 7fps without anything happening is unplayable enough but gets worse when you do anything.

Have you tried running in 32-bit mode? I wasn't even aware there was a 64-bit patch, but running in 64-bit surely won't give any real tangible performance increase here.

The 32bit EXE doesn't even Run, not matter what mode and right I give it. You only get 64Bit EXE if you get the directly game from Origin, from what I gathered. The 64bit version is not about perfomance increase, it's about (supposed restoration of) compatibility with W7x64.

The 64bit EXE starts, loads for sometime and then crashes to desktop.
Patching the game to 1.1 or 1.2, there are some reports that 1.21 breakes it again on W7x64.
HD 3000 drivers etc are the most recent to date. (.2932) and dxdiags reports no errors.

Crysis 2 (and 300 other post 2008 games) run like charm on my system.

The only other game that gave me trouble this big was KOTOR (PC)
It never worked for me without disabling ingame movies.

I for myself and situation found a perfectly working .execution-only solution near Port Royal.
When bucanneers have to do the job of the Govener and are better at it, no wonder the state is in the state it is in.

Now that makes you wonder why I am discussing Sid Meier's Pirates Gold! all of a sudden

If a folder called bin32 really isn't in the Crysis folder, then you're absolutely without a 32-bit option, which is just a bit odd really!
So then in bin64, there should be two .exe's one crysis.exe and the other crysis64.exe. My understanding is that they should be the same, but just try running either of them, with the Vista SP2 compatibility mode and Admin privileges turned on.
Also, if you add "-dx9" to the relevant .exe's boot options (I'm sorry, I forget the name, but it's under properties) that might help any issues you're having with DX10... If running it from a desktop shortcut, right click that and, leaving a space after the .exe, add the -dx9 to the target description.
